No to low power

Hello, I have an 03 Tacoma 4x4 2.7L Manuel. It has 503,000 miles and I just installed a new motor from Frazier Engines. I replaced everything and I mean everything new with the motor swap. All parts were purchased via Oreilly’s except for injector inserts that had to come from Toyota. I just changed oil for the first time on the new motor and after three days I have zero power. I can just make 20 mph with a heavy throttle. I removed all exhaust and replaced the fuel pump with no change. MAF is reading correct and I am only getting 02 codes and a system purge code that has been there for a long time. Other than that no other codes. Check engine light is not flashing and I have correct compression on all cylinders. Plugs are not fouled and all coils are good. No knocking or coolant in the oil.

 

Has it ran good since you put it in….

 

Yes it ran great like it did when I bought it new. Was an immediate change.
